Developing the best conditions

For sustainable buildings with high comfort and low energy demand


More than ever before, buildings nowadays have to fulfil a variety of requirements: they shall constitute a healthy living and working space by offering visual, thermal and acoustic comfort and coziness; they shall have the lowest energy consumption possible and should be efficiently operable. Building engineering physics will therefore become more and more important in the design process- and individual.

iproplan® does not work with prefabricated standardized solutions.


Our specialized engineers consider every building in connection with all of its influencing factors: heat, humidity, sound, ventilation. Whether it is inside or outside. And always in accordance with the respective concept of usage.


In terms of building engineering physics we offer comprehensive planning services in the fields of heat protection, moisture protection, building acoustics and room acoustics, we prepare expert reports and carry out relevant measurements and simulations. Furthermore, the competent staff of our building engineering physics department is involved in every planning process at iproplan®. This is how we achieve the optimum comfort of use together with the required energy efficiency and we ensure at the same time that damage to the building cannot even occur. Together we create better buildings.
